Specification of Letters Patent.

lPatented Oct. 19, 1920.

Application filed February 4, 1919. Serial No. 274,907.

To all whom t may concern:

Be it known that I, FREDERICK R. PAYNE, a citizen of the United States,residing at Chicago, in the county of CookA and State of Illinois, haveinvented new and useful Improvements in Invalids Beds, of which widthsor angles to suit the convenience of the patient, and dispose the partsin different positions as occasion may demand.

A further object of the invention is to produce a sectional-bottom whichmay be applied to the side rails of an ordinary construction ofbedsteads and wherein the sections comprising the bottom are relativelyadjustable to assume different angles and effectively locked when soadjusted `as well as when the sections are brought to alinement.

With these and other objects in view, the invention, consists in thefeatures of construction, combination and arrangement of parts,hereinafter described Land claimed, reference being had to theaccompanying drawings, in which y Figure 1 is a perspective view ofthe1mprovement. Y

Fig. 2 is an` approximately central longitudinal view through the same,the sections of the bottom being arranged angularly with respect to eachother. n f

view of the center The bedstead is broadly indicated by the numeral 10,and the side rails, removably connected to the corner posts of the headand foot of the bedstead by the numerals 11.

To the side rails 11, at the center thereof are connected or may beformed, oppositely arranged depending brackets 12 which are preferablyVeshaped in plan. `The brackets have alining openings which providebearings for a shaft 13, the said shaft being held by collars, or by anysuitable means against longitudinal movement,and the said shaft havingone or if desired both of its ends squared in cross section asindicatedby 14, and these squared ortions are designed to yreceive the socket o asuitable handle whereby the shaft 13 may be rotated. Keyed orv otherwisesecured to the shaft, and preferably contacting with the brackets 12 aretoothed wheels 15 oneor both being preferably engaged by aspringvpressed dog 16, although any other suitable means may be providedfor holding the shaft 13 against turning. y

- The bed bottomfcomprises a central section and end sections which arearrangedbetween the side rails 11. The center section, in the preferredembodiment of the improvement includes parallel side members 17 havingtheir ends formed with depending portions 18 and a connecting member 19for the said depending portions 18. Thus the central section 2O is inthe Vnature of a frame, being substantially rectangular in plan and Ushaped in end elevation. The side members 17 are preferably providedwith centrally arranged outwardly extending trunnions 21 which arereceived in bearing openings in the side rails 11, the trunnions and thebearings therefor being arranged directly labove the shaft 13. Securedto each of the sides 17 of thev central member 20 isV an arched rack 22,and the teeth of these racks are engaged by the toothed wheels 15 of theshaft 13. It will thus be apparent that by turning the shaft 13 thecenter section 20 may be tilted on its trunnions 21 to arrange vthe sameat a desired angle with respect to the sides 11 of the bedsteadfand maybe held at such angle by the (1o-engagement of the spring dogs 16 withthe toothed wheels 15. n

and being inturned, and upon these flanges may rest suitable slats whichsupport the springs for the mattress.

The end frames, while of a similar construction are indicated fordistinction by the numerals 23 and 24 respectively. The section 23 willhereinafter, for convenience be referred to as the head section, thesame being arranged adjacent the head post of the bed, and the section24 will be referred to as the foot section.

Both the sections 23 and 24 are in the nature of a Ushaped frame eachpreferably constructed of an angle-iron, or otherwise Ahaving' theirlower edges providedwith inturned flanges 25. The side members 26 of therespective frames, at the free ends thereof are formed with or haverigidly secured thereon arched toothed segments 27, andupwardofthesegmentsthesaid side members 26 are provided with outstandingtrunnions designed to be received in bearing openings in the ends of theside members 17 of the central frame 20, or may be otherwise pivotallyconnected with the said ends of the said sidemembers as indicated by thenumerals 28. The flanges 25 may be notched to receive slats or maydirectly receive the frame, the frames having each the section of amattress or parts of a single mattress resting thereon, or on thesprings for such mattress.

The depending members 18, at the ends of the side members 17 of thevcenter frame 2O are provided with alining openings forming bearings forshafts 29, the said shafts being held against longitudinal movement inany desired or preferred manner, and the said shafts having keyed orotherwise secured thereon toothed wheels 30, which mesh with the toothedsegments. The ends of the shaft may be cranked or may be squared incross section to receive the sockets of crank handle members, or thecrank handle, which is designed to engage with the ends of the shaft 13,and by turning the shafts 29 it will be apparent that the head and footsections 23 and 24 may be swung to a desired angle with respect to thecenter section of the frame 20. To hold the shafts against rotation andto hold the sections 23 and 24 at desired inclinations, the toothedwheels 30 may be engaged by spring pressed dogs 31, or any other desiredmechanism may be employed for this purpose. l

Y In the construction illustrated in Figs. 6 to 8 of the drawings thecenter frame 32 for the bottom has its side member centrally pivoted, asat 33 to the side rail 34 of the bedstead 35. The sides of the saidcenter member or frame 32 are providedwith depending arched racks 36which are engaged 4by toothed wheels 37 secured on a shaft 38 journaledin bearing openings n brackets 39 secured to and depending from the siderails 34`of. the bedstead 35. The ends of the shaft 38 are bent toprovide a crank or the said ends may be shaped to receive the vsocket ofa crank handle whereby the shaft may be turned and consequently swingthe center section 32 on its pivots 33 to bring the same at a desiredinclination with respect to the bedstead. The toothed wheels 39 on theshaft 38 are preferably engaged by spring pressed dogs 40 so that theshaft is normally held against turning, and the dogs are, of course,released when it is desired to turn the shaft and tilt the center frame32. The side members ofthe center frame are in the nature of angle barsto receive the slats which support the spring of the mattress, or themattress may rest directly upon the inturned flanges or horizontalportions of .the saidangle bars.

The end frames, forthe bottom, indicated by the numerals 41 and 42respectively are in the nature of U-shaped members, and are alsoconstructed of angle bars, the horizontal flanges of which are inturned.The side arms or members of the frames 41 and 42 are provided withoutstanding trunnions, at the outer ends thereof, the said trunnionsbeing indicated by the numerals 43 and being received in bearingopenings in the side rails 34, or in the vertical end portions 44 ofsubstantially U-shaped cross pieces 45, the flanged ends 44'of the samebeing secured to the side rails 34 of the bedstead 35.

The ends of the side members of the frames 41 and 42 are formed with orhave secured thereon depending toothed segments 46 which are engaged bytoothed wheels 47 on a shaft 48 that passes through bearing openings inthe flanged sides 44 of the connecting members 45. The "shaft is heldagainst longitudinal movement either by contact of the toothed wheels 47with the inner faces of the ends 44 of the members 45, or in any otherdesired manner, and the projecting ends of the shafts may be cranked orarranged to receive the socket of a crank handle thereon. The shaft 48is normally held from turning, preferably through the medium of springpressed dogs 50 engaging with the toothed wheels 47 but any otherdesired means may be provided for this purpose. With this constructionthe end sections may be adjusted independent of each other andindependent of the center section duces a very strong structure but theelements constituting the same being round persons reclining in crosssection will not Collect dust thereon so that thebed may be easilycleaned.

Having thus described the invention, what I claim is:

In combination With the side rails of a bedstead having dependingbrackets at the center thereof, of a bottom frame between the rails andincluding a center frame and end frames, each of said frames havinginturned flanges, and the end frames being substantially U-shape inplan, toothed segments on the inner ends of the end frames, archedtoothed segments on thekcenter frame,

a pivotal connection between the end frames and the central frame, ashaft journaled in the mentioned brackets, toothed Wheels thereonmeshing with the arched segments, lockingy means for the last mentionedshafts journaled in the eenterframe, toothed Wheels on said shaftsmeshing with the toothed 'segments of the end frames, rand looking meansfor the last mentioned l toothed Wheels.

In Witness whereof I aix my signature.

FREDERICK R. PAYNE.
